OvmfPkg: remove Xen support from OvmfPkg*.dsc, in favor of OvmfXen.dsc

[edk2-devel] [PATCH 22/43] OvmfPkg: drop PcdPciDisableBusEnumeration from the IA32, IA32X64, X64 DSCs

Posted by Laszlo Ersek 4 years, 8 months ago

With the Xen-dependent PcdSetBoolS() call removed from
OvmfPkg/PlatformPei, the "OvmfPkgIa32.dsc", "OvmfPkgIa32X64.dsc",
"OvmfPkgX64.dsc" platforms never write "PcdPciDisableBusEnumeration". This
means we don't need a dynamic default for the PCD in the DSC files; it
could be declared Fixed-at-Build.

However, because the PCD's default value in "MdeModulePkg.dec" is FALSE,
remove the (same-value) platform defaults altogether.
